The answer is that the idea of being "created in the image and likeness" primarily concerns the inner essence of a person—his soul, word (intellectual ability), and spirit—rather than solely his external, physical characteristics.

Inner Divine Nature

The answer is that the idea of being "created in the image and likeness" primarily concerns the inner essence of a person—his soul, word (intellectual ability), and spirit—rather than solely his external, physical characteristics. In other words, individual differences, including disabilities, do not deprive a person of his fundamental spiritual nature, which is defined by deeper qualities such as intellect, kindness, and the desire for God.

For example, one source notes:
"Therefore it is said that man was created in the image and likeness of God (Gen 1:26). 'In the image'—as the image of the Being and as the likeness of the Coexistent: ... Every rational nature is in the image of God, but only the good and wise ones are in His likeness." (source: link txt)

This quote emphasizes that the mere possession of rationality is already a sign of being created in God's image. Moreover, the full reflection of divinity (i.e., likeness) is manifested through the highest moral and spiritual qualities that persist regardless of physical limitations.

Another source elaborates on the inner structure of a person, which provides the basis for understanding the divine image:
"The intelligent soul is likened to the Father; the word, which is generated by the soul, to the Son; the spirit issues, having an inseparable union with the soul and the word. ... thus, a person, created in the image of God, carries within him the likeness of God: soul, word, and spirit. [...]" (source: link txt)

Here it is explained that it is precisely these immortal, inner aspects of a person that constitute his true divine likeness. Consequently, even if a person's external manifestations vary—whether in physical traits or disabilities—his essence, memory, intellect, and spirituality remain a reflection of God.

In this way, issues of individual differences, including disabilities, relate to the religious idea that the authentic "image of God" is measured not so much by external perfection but by the inner essence inherent in every person as a result of his creation. Hence, physical deviations or characteristics do not diminish the inherent worth embedded in each individual as a bearer of this spiritual nature.
